Sigma 85mm f/1.4 DG HSM Art Lens for Canon EF Black (321954) KSA Version with KSA Warranty Support

SIGMA 85 mm F1,4 DG HSM Art

Portrait photographers require an attractive bokeh that only offer large-diameter lenses, as well as a superior resolution. Since the SIGMA 85mm F1.4 DG HSM | Art representing the high standards of the Art product line, it meets both requirements at the highest level.

The extremely precise bokeh makes it possible, for example, to focus on the pupil of the model and at the same time make the eyelashes blur. Add to this impressive bokeh, the focus area is extremely high resolution. In the SIGMA 85mm F1.4 DG HSM | Type 14 lens elements are built in 12 groups - a remarkable structure that brings the ultra-high resolution of the lens. Therefore, this lens is an excellent choice for full-frame DSLRs with a resolution of 50 megapixels and more.

Outstanding resolving power and minimized chromatic aberration contribute to the 85mm F1.4 DG HSM | Art is the ultimate lens for portraits

DG Lenses

The DG lenses are designed for demanding use on digital SLR cameras up to full format. These lenses illuminate the full 35mm-KB format and are therefore equally suitable for use on 35mm film SLR cameras as well as digital SLR cameras. By using modern tempering techniques, ghosting is successfully eliminated by reflections on the surface of the sensor while achieving a balanced color balance.

ASP - aspherical correction

Normally, near-edge rays are more strongly refracted toward the center when passing through a lens than near-axis rays. The aspherical correction of an optical system eliminates numerous aberrations at once. The sharpness is achieved over the entire image field and the distortion is reduced to a minimum. Almost all our lenses are equipped with at least one aspherical lens element.

HSM - Hyper Sonic engine

HSM Ultrasonic Motor (Hyper Sonic Motor) - HSM lenses use a motor powered by ultrasonic waves. This technology provides you with a very fast, accurate and almost silent type of auto focus. Two different types of HSM ultrasonic drive are used in our lenses. First, the HSM ring motor, which is mainly installed in the high-quality EX lenses. This HSM drive allows you to manually engage in AF operation at any time. On the other hand, an HSM micromotor is primarily used in compact lenses, the so-called all-round zoom lenses. Here a manual intervention in the AF operation is not possible.

IF - internal focusing

For inner focus lenses, only one or more lens groups are moved inside the lens for focus. This results in many advantages, as with rear-focus lenses: the inner focus ensures faster and quieter focusing. With IF lenses, the length of the lens remains constant during focusing and the front lens does not rotate, allowing you to conveniently use polar filters and a tulip-shaped lens hood. Since the length of the lens remains constant during focusing, there is no noticeable shift in focus during focusing. As a result, the lens is well balanced at all times.
